The width of the shovel blade is 20 cm, the thickness is 3 mm. The person presses the shovel with a force of 30 N. Determine its pressure on the soil.
To solve this problem, you first need to translate the indicated dimensions of the shovel blade into meters.
Since 1 meter is 100 centimeters, and 1 centimeter is 10 millimeters, we get:
20 cm = 20/100 = 0.2 m (shovel blade width).
3 mm = 3/10 * 100 = 3/1000 = 0.003 m (shovel blade thickness).
Determine the area of the shovel blade.
To do this, we multiply the width and thickness of the shovel blade among ourselves.
Will be:
S = 0.2 * 0.003 = 0.0006 m2
Determine the pressure on the soil.
P = 30 / 0.0006 = 50,000 Pa.
Answer: The pressure on the soil is 50,000 Pa.
